Abstract
Silicon is an important alloying component of stainless steels for high temperature service but the specific role of this element in the oxidation process is relatively poorly understood. In this work, experimental alloys based on Fe–20Cr–35Ni with either 0·5% or 2% silicon have been produced and studied using isothermal, discontinuous and cyclic oxidation testing at 700°C and 1000°C in dry and moist air atmospheres. Evaluation was by means of thermogravimetry, surface analysis, microscopy and application of a simple cyclic oxidation model.
